A Review on Sisal Fiber Reinforced Polymer Composites

Abstract

The global demand for wood as a building material is steadily growing, while the availability of this natural resource is diminishing. This situation has led to the development of alternative materials. Of the various synthetic materials that have been explored and advocated, polymer composites claim a major participation as building materials. There has been a growing interest in utilizing natural fibres as reinforcement in polymer composite for making low cost construction materials in recent years. Natural fibres are prospective reinforcing materials and their use until now has been more traditional than technical. They have long served many useful purposes but the application of the material technology for the utilization of natural fibres as reinforcement in polymer matrix took place in comparatively recent years. Economic and other related factors in many developing countries where natural fibres are abundant, demand that scientists and engineers apply appropriate technology to utilize these natural fibres as effectively and economically as possible to produce good quality fibre reinforced polymer composites for housing and other needs. Among the various natural fibres, sisal is of particular interest in that its composites have high impact strength besides having moderate tensile and flexural properties compared to other lignocellulosic fibres. The present paper surveys the research work published in the field of sisal fibre reinforced polymer composites with special reference to the structure and properties of sisal fibre, processing techniques, and the physical and mechanical properties of the composites.Key words: sisal fibre, polymer, composites, structure, properties COMPÓSITOS POLIMÉRICOS REFORÇADOS COM FIBRAS DE SISAL RESUMOO uso da madeira como material de construção continua crescendo mundialmente enquanto a disponibilidade deste recurso natural está diminuindo. Esta situação tem conduzido ao desenvolvimento de materiais alternativos. Dentre os vários materiais sintéticos que têm sido explorados, os compósitos poliméricos reivindicam e buscam uma maior participação como material de construção. Nos últimos anos tem se observado um crescente interesse na utilização de fibras naturais como reforço de matrizes poliméricas para a produção de materiais de baixo custo. As fibras naturais são reforços com grande potencialidade e seu uso tem se dado de forma mais tradicional do que científica. Elas têm se prestado a inúmeras aplicações ao longo do tempo, mas a aplicação da tecnologia dos materiais visando a sua utilização como reforço de matrizes poliméricas é relativamente recente. As dificuldades econômicos e sociais observadas em muitos dos países em desenvolvimento, onde as fibras naturais são abundantes, requerem que cientistas e engenheiros apliquem tecnologias apropriadas para utilizar estas fibras da forma mais eficiente possível, de tal maneira que se possa produzir materiais compósitos poliméricos de boa qualidade visando a atender a demanda da população por habitações e componentes habi...

Chemical and morphological characterization of <em>Agave angustifolia</em> bagasse fibers

“…Palabras clave: análisis térmico, composición química, cristalinidad, morfología, pruebas mecánicas. ETHNOBOTANY R ecently, research on plant fi bers has been increasing due to the abundance of these materials and their status as renewable resources (Joseph et al, 1999;Ghali et al, 2006;Lucena et al, 2009;Ku et al, 2011;Kestur et al, 2013). Consequently, this focus has led to further research on the specifi c characterization of individual plant fi bers such as bamboo, okra, sisal, and henequen (Mishra et al, 2004; Bé-akou et al, 2008;De Rosa et al, 2010;Liu et al, 2012;Arrakhiz et al, 2013) and studies on composite materials (Mohanty et al, 2002;Herrera-Franco and Valadez-González, 2005;Faruk et al, 2012).…”

Tarımsal atıklardan elde edilen sürdürülebilir tekstil lifleri: Ananas yaprağı lifleri

“…Beyazımsı renge sahip, yumuşak ve ipek gibi parlak lifler olan PALF lifleri, kopma mukavemeti yüksek liflerdir [12,17,21,41,66,107]. PALF liflerinin yaş ve kuru mukavemetleri karşılaştırıldığında sıra dışı bazı sonuçlar göze çarpmaktadır [27,108].…”

Ananas lifleri ile diğer liflerin özelliklerinin karşılaştırılması (Properties comparision of pineapple leaf fiber with other natural fibers) [26,32,93,99,109] ) olan ananas yaprağı liflerinin sert bir lif olduğu, ananas liflerinin mikrofibril açısı ve yüksek selüloz oranı sayesinde üstün mekanik özelliklere sahip olduğu kaydedilmiştir [6,7,12,20,27,45]. Bazı kaynaklarda mikrofibril açısı 5-15 o arasında değişir olarak belirtilmektedir [26,46].…”

“…Sadece tekstil materyallerinde değil tekstil liflerinin kullanıldığı tüm alanlarda sentetik lifler yerine alternatif oluşturabilecek benzer özelliklerde doğal liflerin kullanılması mümkündür. Özellikle kompozit malzemelerde güçlendirici olarak kullanılabilen çok sayıda doğal lif çeşidi bulunmaktadır [6][7][8][9][10][11][12][13][14]. Ayrıca her geçen gün azalan petrol kaynakları göz önüne alındığında, her yıl kendiliğinden yenilenen doğal materyallerin kullanımı hem çevresel hem de ekonomik anlamda avantajlı hale gelmektedir [7,9,15,16].…”

Fabrication Techniques of Micro/Nano Fibres based Nonwoven Composites: A Review

“…Fibres are strong, coarse and inflexible in nature, which makes it reasonable to concern as fortifying material in the composite system. In the last few decades, various forms of synthetic/natural fibres are examined for utilization as reinforcement in composites system [10][11][12][13][14][15][16][17][18][19][20]. For example, synthetic fibres namely glass, rayon, aramid, nylon, carbon, and polyester are comprehensively utilized as reinforcement in polymer matrices [11,12].…”
